First 90 Days as a CTO
The first ninety days set how people remember you, not because of what you build, but because of what you understand before you touch anything. Pick your situation, get a plan.
After Michael Watkins, The First 90 Days
Which situation are you walking into?
Michael Watkins calls these the STARS situations. Naming yours changes everything downstream, a turnaround rewards week-one action; a realignment punishes it.
Learn, and earn the right to be heard
- Get your success metrics from the CEO in writing
- One-on-ones with every direct report and their reports
- Understand the business: revenue, burn, the growth target
- Sit in on a customer call; read a week of support tickets
- Ship nothing structural, just learn the terrain
By day 30: A one-page diagnosis + a draft plan, and your first check-in with the boss.
Turn observations into a plan
- Join the on-call rotation; feel the real workflow
- Baseline delivery metrics (deploy freq, lead time, change-fail, recovery)
- Identify the two or three roles that unblock everything
- Ship one small quick win, not a rewrite
- Share observations weekly, without premature judgment
By day 60: A diagnosis + a technology roadmap the business can read.
Execute, as systems, not heroics
- Implement one or two durable improvements, properly
- Publish the technology strategy and walk the team through it
- Set the boring cadences: monthly Q&A, weekly update, ops review
- Start closing the priority hires personally
- Protect your own pace so you can lead, not just react
By day 90: Clarity, a roadmap people believe, and the quiet sense someone’s in control.
Watkins’ research puts a number on it: leaders who onboard deliberately reach the point of contributing more than they consume roughly 40% faster than those who wing it. The 90 days aren’t a probation period, they’re the highest-leverage time you’ll ever have in the role.
The 30/60/90 structure and the STARS situations are drawn from Michael D. Watkins, The First 90 Days (Harvard Business Review Press). This is an original interpretation for technology leaders, not a reproduction of the book.
